• Proven experience with complex, distributed software systems, preferably within regulated, defence, government, security or mission-critical contexts.
• Strong system-level understanding across back-end and front-end domains, enabling you to define fundamentals and guide implementation.

• Solid knowledge of software quality assurance , static analysis, and code quality tools (e.g., SonarQube)

• Cyber security domain experience.
• Training/simulation platform development experience.
• Security clearance or experience with classified projects.
• Experience structuring technical work in early-phase programmes.
